A benign lesion called an antrochoanal polyp (ACP) begins in the mucosa of the maxillary sinus, grows into the middle meatus through the accessory ostium, and then protrudes posteriorly into the choana and nasopharynx. The most frequent presenting symptoms are nasal discharge and blockage. The reasons for unilateral nasal obstruction should be included in the differential diagnosis. The primary methods of diagnosis for ACPs are computed tomography scans and nasal endoscopy, and surgical intervention is the only course of therapy available. For the entire removal of ACPs, powered instrumentation during functional endoscopic sinus surgery (FESS) and FESS itself are incredibly safe and successful treatments. To stop recurrence, surgeons should concentrate on determining the precise cause and scope of the polyp. Recurrence of an antrochoanal polyp is nearly invariably caused by incomplete resection.
